19 Claims. o1.2142s) My invention relates tothe general arrangement of a Vmachine ior use in connection with retort lay-product coke ovens and more especially to the manner of mounting the mechanism 5 on a single carriage for removing and replacing the doors on the pusher side of the oven, ejecting the cokefrom the ovens, sealing the space around the. doors after replacement and then leveling the `coal after it has been charged into 110 the oven.

2o into the oven through an opening usually in the top portion of the door or above the same.

A mud buggy is also sometimes installed on the carriage of the machine which is used Yfor sealing the space around the door after the coke has been ejected from the oven and the door replaced and before the oven is recharged with coal.

While thought and time have been expended to improve the mechanical operation and durability of this equipment, its operationslon account of the different tools being mounted in fixed spaced relation to each other usually take place one at a time, with theresult that while the men working with this machine could easilyr do more Worlgtheir output is limited by the speed of operation of the machine. This lost time consumed by the carriage in traveling or moving back and forth to place itself in position to use its various tools as needed to complete the cycle of operation.

From time to time bituminous coal is charged into one or more of the ovens of the battery while similar charges in other ovens are being coked. As the charges in various ovens form- 45 ing a battery or a number of batteries are in different conditions, some of the coal being green, other ovens filled Vwith coal that is partially coked, still others with coke that is practically nished, this gives a fairly constant amount of distillate gas supply which is gathered in a co1- lecting mainfrom which point it is delivered to by-product recovering devices which `separate the by-product from the gases, and a portion of 55" the gas is then iinally returned to the battery PATE OFFICE for heating the same, while the excess gas is used for commercial purposes.

The finished charges of coke in the ovens are pushed in a coke plant in series of every ith oven, tenth or some other combination that satises themanagement that the heat distribu tion through the battery of ovens is the best they can possibly obtain.

My machine is designed in such a manner that it can be built to meet the conditions of any particular plant.

For illustration the one shown in thedrawings covers the construction for a five oven series but it will be readily understood that by varying the distance between the leveling barand door manipulator and pusher ram any pushing series may be obtained.

With my machine it is possible for the carriage to remain stationary While operations after ejecting the oven.

be oper- Another object ofk my invention relates to the manner of mounting the door manipulator and pusher ram on a pivoted platform in horizontal radial alignment with the pivotal point which allows the outer end to be adjusted without moving the carriage.

Another object of my invention relates to the particular manner of mounting and operating eating stroke.

Other objects will appear hereinafter. Having given a general description of my invention I will now, in order to make the same more clear, refer to the accompanying two sheets of drawings in which like characters refer to like parts.

with a portion of the battery shown in section;

Fig. 2 is a side elevation of the machine shown in Fig. 1; and

Fig. 3 is a side elevation of the leveling bar mechanism taken on the line 3-3 of Fig. 1.

In the drawings which are shown more or less diagrammatically the numeral 1 indicates the carriage provided with rollers 2 journaled in bearings mounted on the girders 3 and adapted to travel on the rails 4.

The axles 5 of two of the rollers 2 have gears 6 mounted thereon meshing with pinions 7 on the ends of a drive shaft 8, having a gear 9 mounted centrally thereon for meshing with a pinion 10 on the shaft of a motor 11 for rotating the shaft for operating the carriage.

Secured on top of the carriage near the rear end at one side thereof is a center bearing plate 12 having a central perforation adapted to receive the king bolt 13 extending from a bearing plate 14 secured to the under side of the pivoted platform 15 near the inner end, the forward and intermediate portion of the platform being supported on track segments 16 and 17 by means of rollers 18 which are secured to the platform by means of brackets, the forward end of the pivoted platform being limited in its lateral movement by means of stops 19. Standards 20, 2l, and 22 are mounted at spaced intervals on the platform in which are mounted idler rollers 23 for guiding a pusher ram 24 which has a rack formed on its under side for meshing with a pinion 25 on'shaft 26 journaled in the bearing' 22, the outer end of said shaft being connected by means of reduction gearing 27, driven by means of a motor 28. Mounted in the platform 15 laterally thereof at one side of the pusher ram 24, is a door manipulator 29, mounted in standards and 31 between idler rollers 32 for guiding the same. The Linder side of the shaft of said door manipulator has a rack formed thereon as at 33 meshing with a pinion 34, the shaft of which is journaled in standard 31 and connected with reduction gearing 35 and actuated by means of a motor 36. The forward end of the door manipulator is formed with hooks 37 for engaging the lugs 38 on doors 39 for closing the pusher side of the coke ovens 40. In order to adjust or swing the outer end of the platform 15 with the pusher ram 24 and the door manipulator 29 mounted therein, a

motor 41 is mounted on the front end of the platform which is connected by means of gearing 42 to a rack 43 formed on the track segment 17.

A leveling bar 44 is mounted laterally of the pivoted platform on one side of the carriage l, the forward end of the leveling bar being supported between standards 45 and idler rollers 46 while the rear end of the leveling bar is guided between posts 47 and idler rollers 48, mounted on a car 49 supported on wheels 50 engaging a track 51, said car having a motor 52 and reduction gearing 53 for bodily advancing the car and the leveling bar. The motor 52 and gearing 53 connected therewith will advance the leveling bar slowly into the coke oven. When the leveling bar encounters a pile of coal which cannot be leveled by the slow movement of the leveling bar into the oven the leveling bar can be given a short stroke reciprocating motion independent of the motor 52 rby throwing in the motor 54 geared to crank arms 55 and pitmen 56 pivoted to a sector gear 57 journaled on the car body. This sector gear 57 engages gears 58 and has a gear 59 adapted to engage a rack 60 on the under side of the leveling bar.

A mud buggy or bucket 61 is pivoted by means of an arm 62 to a standard 63 which may be swung out when desired for sealing the doors after they have been replaced before charging the ovens. An operators cab 64 is mounted on the carriage in which the controllers (not shown) for operating the different motors may be installed.

The operation of my invention is as follows: After the door of the first oven is removed by means of the door manipulator 29 and the platform 15 swung from the dotted position into the full line position indicated in Fig. 1 of the drawings the pusher ram 24 is then advanced into the oven the full length thereby ejecting the coke from the oven into a coke quenching car or the like receptacle on the opposite side of the battery, the pusher ram 24 is then returned to the position shown in the drawings and the platform swung into the dotted line position and the door replaced in the end of the oven, the carriage will then be advanced a distance equal to ve ovens until the leveling bar properly centered for its operation, the luter man will then swing out his luter box, and start his operation of sealing the door, while he is swinging out his luter box and completing his operation the movable platform 15 holding the pusher ram 24 and door manipulator 29 will swing into position, remove the door of the oven and swing the pusher ram into operating position. The operation of mudding the previous door taken off, taking off the door of the next oven to be pushed and swinging the pusher rain into position for its work will be finished at the same time. The rst oven discharged having been recharged with coal in the usual manner, the control is then thrown in, starting the leveling bar into operation, this can be then left to itself while the operator pushes the coke from the oven, after the coke in the oven has been ejected and the pusher ram retracted into its normal position, the door manipulating machine is operated to replace the oven door, the leveling operation has been compieted and the carriage with the machines mounted thereon moves up another series of five ovens to repeat the cycle.

Although I have described and illustrated my invention in considerable detail, I do not wish to be limited to the exact and specific details thereof, as shown and described, but may use such modifications in substitutions for, o equivalents thereof, as are embraced within the scope of my invention, or as pointed out in the claims.
